Hermann von Helmholtz was born 200 years ago, but his influence on vision research is enduring. His legacy in vision is celebrated visually with anaglyphs that combine portraits of him with illustrations from his publications. Emphasis is directed principally to his Treatise on Physiological Optics. Among the optical instruments Helmholtz invented were the ophthalmoscope, ophthalmometer, and telestereoscope. Mention is made of his investigations into accommodation, colour vision, eye movements, stereoscopic vision, binocular rivalry, and lustre. Helmholtz also presented his analyses of vision and art in several of his Popular Lectures.

赫尔曼·冯·亥姆霍兹 (Hermann von Helmholtz) 出生于 200 年前，但他对视觉研究的影响经久不衰。他的视觉遗产通过将他的肖像与他出版物中的插图相结合的浮雕在视觉上得到了颂扬。重点主要是针对他的《生理光学论文》。亥姆霍兹发明的光学仪器包括检眼镜、检眼镜和望远镜。提到了他对调节、色觉、眼球运动、立体视觉、双眼竞争和光泽的研究。亥姆霍兹还在他的几篇大众讲座中介绍了他对视觉和艺术的分析。
